10^2 + 4* 9 -2^3

First take care of all the exponents.


100 + 4 * 9 - 8

Now do the multiplication.


100 + 36 - 8

Now add and subtract from left to right.


136 - 8


128

Your final answer is 128.

Lets write this out:-

10² + 4 × 9 - 2³

Solve:-

10² = 10 × 10 = 100
100 + 4 × 9 - 2³
2³ = 2 × 2 × 2 = 8
100 + 4 × 9 - 8
4 × 9 = 36
100 + 36 - 8
100 + 36 = 136
136 - 8 = 128

10² + 4 × 9 - 2³ = 128

Good luck! :P
