Answer:

5^3

Step-by-step explanation:

In laws of indices x^2 × x^5. The powers are added when the bases are multiplied and when its division you subtract.

${x}^{2} + {x}^{5} = x ^{2+ 5} = {x}^{7}$

Therefore so 5x×5x^2=5x^3

$5x {}^{1} \times 5x {}^{2} = 5x {}^{2 + 1} = 5x {}^{3}$

Answer:

$x = - 23$

Step-by-step explanation:

$\frac{20 - (40 + x)}{12} \times 10 = 32.5 - 30 = 2.5$

$= > \frac{20 - (40 + x)}{12} = 0.25$

$= > \frac{20 - (40 + x)}{12} = \frac{1}{4}$

$= > 20 - (40 + x) = \frac{12}{4} = 3$

$= > 40 + x = 20 - 3 = 17$

$= > x = 17 - 40 = - 23$
