(125 times 125 times 125 times 125 times 125 = 5^? )
If (a^x = b, b^y = c ) and (c^z = a ), then the value of (xyz ) is:
If (2^{(x-y)} = 8 ) and (2^{(x+y)} = 32 ), then (x ) is equal to:
If (7^a = 16807 ), then the value of (7^{(a-3)} ) is:
If (3^x - 3^{x-1} = 18 ), then the value of (x^x ) is:
If (a^x = b^y = c^z ) and (b^2 = ac ), then (y ) equals:
If (5^{a}=3125 ), then the value of (5^{(a-3)} ) is:
Given that (10^{0.48}=x ), (10^{0.70}=y ) and (x^{z}=y^{2} ), then the value of z is close to:
The value of ([(10)^{150} div (10)^{146}] )
