Answer:

r = 4

Step-by-step explanation:

z ^ (7/10) * z^ ( 33/10)

We know that a^ b* a^c = a^(b+c)

z^ (7/10 +33/10)

z^ (40/10)

z^4

r = 4

1.

$92+\frac{56}{14-x}=100\\\\\frac{56}{14-x}=8\\\\(\frac{56}{14-x})*(14-x)=8*(14-x)\\\\56=(8*14)+[8*(-x)]\\\\56=112-8x\\\\-56=-8x\\\\\\x=7$

2.

$\frac{410-x}{7}+70=120\\\\\frac{410-x}{7}=50\\\\(\frac{410-x}{7})*7=50*7\\\\410-x=350\\\\-x=-60\\\\\\x=60$
