Question

Памгите 25m×3n,если m=8,n=1 5x+8x-3x,еслиx=17

Answer 1

25*8*3*1=600 ,если m=8,n=1

5x+8x-3x=10*17=170 ,еслиx=17

Answer 2

Sure, let's solve the expressions step by step:

1. For 25m × 3n, where m = 8 and n = 1: Substitute the given values: 25m × 3n = 25 * 8 × 3 * 1 Calculate the multiplication: 25m × 3n = 200 × 3 Calculate the final result: 25m × 3n = 600

2. For 5x + 8x - 3x, where x = 17: Substitute the given value: 5x + 8x - 3x = 5 * 17 + 8 * 17 - 3 * 17 Calculate the multiplication: 5x + 8x - 3x = 85 + 136 - 51 Calculate the final result: 5x + 8x - 3x = 170

So, the results are:

1. 25m × 3n, if m = 8 and n = 1, is equal to 600.
2. 5x + 8x - 3x, if x = 17, is equal to 170.
