Question

fast answern me plzzzz

Answer 1

solving the 225 we get 15x15 = 3x3x5x5 = 3^2 x 5^2

now we can see on the right hand side the power is 2

so in the left side equation what should be the value of n to make 5 and 3 to the power 2, and it should be 5

so in the left hand side when you keep n = 5 you will get 5^2 x 3^2 that is equal to the right hand side hence n = 5

Answer 2

261
$261n$
