Question

Which calculation can be used to find the value of p in the equation p3 = 8?

p equals cube root of 8
p equals 3 multiplied by the square root of 8
p equals 2 multiplied by square root of 8
p equals square root of 8

Answer 1

hint:
I can rewrite your equation as below:
\[\Large {p^3} = {2^3}\]
now, two powers with same exponent are equal each other if they have the same basis too

Answer 2

@Michele_Laino I dont really understand

Answer 3

for example, the solution of this equation:
\[\Large {k^3} = 343\]
is \( \large k= 7 \)
since:
\[\Large 343 = {7^3}\]
