Question

An expression is shown.
5 x 20 x 10²
What is the value of the expression? ​

Answer 1

Answer: 1×10⁴

Explanation:

5 x 20 x10²

First multiply and forget about 10² for now:

5 × 20= 100

Then we add back the ×10²:

100×10²

Then we simplify:

1×10⁴

You can check the answer since:

5 × 2000= 10000

When simplified = 1×10⁴

Answer 2

10,000

Explanation:

using PEMDAS we multiply the exponent first to get 5*20*100, now they are all multiplicative so we go left to right, 100*100 which is 10,000
