Q. If 153=2(z+z)n, then what is the value of 2n(2z)−193 ?Choose 1 answer:(A) −113(B) −40(C) 40(D) 113
Divide by 4: Now, let's solve for zn by dividing both sides of the equation by 4.zn=4153zn=38.25
Find 2n(2z): Next, we need to find the value of 2n(2z). Since we know zn, we can multiply it by 2 to find 2n(2z). 2n(2z)=2×zn 2n(2z)=2×38.25 2n(2z)=76.5
Subtract 193: Now, we subtract 193 from the value of 2n(2z) to find the answer to the problem.2n(2z)−193=76.5−1932n(2z)−193=−116.5
