Question 1 of 50
1. Question
Topic: Multiplication With Standard Form.
Please have pen and paper handy to show workings out. 📝
(7 × 10⁴) × (2 × 10³)
-
× 10
⌨️ Enter your answer in standard form in the fields provided.
CorrectIncorrectHint
Rules for Multiplying and Dividing Numbers in Standard Form
Standard form is written as A × 10n, where:
– A is a number between 1 and 10.
– n is an integer representing how many places the decimal point has moved.
To multiply or divide numbers in standard form, follow these steps:
Step 1: Use the rules of indices for the powers of 10:
– When multiplying, add the powers (n values): 10n1 × 10n2 = 10n1 + n2.
– When dividing, subtract the powers (n values): 10n1 ÷ 10n2 = 10n1 – n2.
Step 2: Multiply or divide the A coefficients:
– Multiply the A values when multiplying the numbers.
– Divide the A values when dividing the numbers.
Step 3: Adjust the result to ensure the final A coefficient is between 1 and 10:
– If A is greater than 10, divide A by 10 and increase the n value by 1.
– If A is less than 1, multiply A by 10 and decrease the n value by 1.
Tip: Always double-check your calculations to ensure both A and n are correctly adjusted for the final result!

– When multiplying, add the powers (n values): 10n1 × 10n2 = 10n1 + n2.
– When dividing, subtract the powers (n values): 10n1 ÷ 10n2 = 10n1 – n2.
Step 2: Multiply or divide the A coefficients:
– Multiply the A values when multiplying the numbers.
– Divide the A values when dividing the numbers.
Step 3: Adjust the result to ensure the final A coefficient is between 1 and 10:
– If A is greater than 10, divide A by 10 and increase the n value by 1.
– If A is less than 1, multiply A by 10 and decrease the n value by 1.
Tip: Always double-check your calculations to ensure both A and n are correctly adjusted for the final result!

Rules for Multiplying and Dividing Numbers in Standard Form
Standard form is written as A × 10n, where:
– A is a number between 1 and 10.
– n is an integer representing how many places the decimal point has moved.
To multiply or divide numbers in standard form, follow these steps:
Step 1: Use the rules of indices for the powers of 10:
– When multiplying, add the powers (n values): 10n1 × 10n2 = 10n1 + n2.
– When dividing, subtract the powers (n values): 10n1 ÷ 10n2 = 10n1 – n2.
Step 2: Multiply or divide the A coefficients:
– Multiply the A values when multiplying the numbers.
– Divide the A values when dividing the numbers.
Step 3: Adjust the result to ensure the final A coefficient is between 1 and 10:
– If A is greater than 10, divide A by 10 and increase the n value by 1.
– If A is less than 1, multiply A by 10 and decrease the n value by 1.
Tip: Always double-check your calculations to ensure both A and n are correctly adjusted for the final result!
