Question

Work out ( 2 × 10 5 ) × ( 3 × 10 4 ) Give your answer in standard form.

Answer 1

Hello, I'd like to answer your question. So first, you write an equation for this question:

Equation: (2×10^5)×(3×10^4)

(2×10^5)×(3×10^4), then here are the steps:

Always use the Order of Operation.

() - Parenthesis

^x - Exponents

×/÷ - Multiplication/Division

+/- - Addition/Subtraction

So, in the parenthesis, there is an exponent. We solve that first.

10^5=100,000

10^4=10,000

Now, multiply these two.

(2×100,000)=200,000

(3x10,000)=30,000

Now, the answer is:

200,000×30,000=6000000000

Thus, we can write it simplified.

6×10^9 is the answer.

Answer 2

6 × 10^9

Explanation:

( 2 × 10^5 ) × ( 3 × 10^4 )

Rearrange.

2 × 3 × 10^5 × 10^4

Multiply and apply the law of exponents.

6 × 10^(5+4)

6 × 10^9
