Question

150*10^(-3)*120 ans=18 how to solve it ​

Answer 1

Step-by-step explanation:

a^-m =1/a^m

150 ×(1/10³) ×120

150 ×120 / 1000 = 18000/1000=18

Answer 2

The value of the given expression will be 18.

Given:

an expression: 150 × 10⁻³ × 120

To Find:

we need to find the value of the given expression

Solution:

we know that when a given number has a negative power, it is equal to the reciprocal of the number raised to the positive power.

Mathematically, this means-

x⁻ᵃ = 1/xᵃ

⇒ 10⁻³ = 1/10³

so, the given expression can be re-written as follows-

150 × 1/10³ × 120

solving it further-

= 150 × 120 × 1/1000

= 18000 × 1/1000

= 18000/1000

= 18

Thus, the value of the given expression comes out to be 18.
