Answer:
1). x = 81
2). x = 84
Step-by-step explanation:
1). By applying geometric mean theorem in the given triangle,
56x = (18√14)²
56x = 4536
x =
x = 81
2). By applying geometric mean theorem,
16x = (8√21)²
16x = 1344
x =
x = 84
Answer:
n = - 4
Step-by-step explanation:
note that 625 = , then
=
=
Since the bases on both sides are equal, both 5 then equate the exponents
n = - 4
