Find the absolute value of 3 4 3

We know that, In general, for any rational number p and a positive integer n , p n = p × p × p . . . . . . . × p n t i m e s and p n is called the n t h power of p . And if p q q ≠ 0 is any rational number and n is any integer, then p q n = p n q n Then, 3 4 3 = 3 3 4 3 = 3 × 3 × 3 4 × 4 × 4 = 27 64 Therefore, the absolute value of 3 4 3 is 27 64 .

Write the absolute value of - 7 8 2

We know that, In general, for any rational number p and a positive integer n , p n = p × p × p . . . . . . . × p n t i m e s and p n is called the n t h power of p . And if p q q ≠ 0 is any rational number and n is any integer, then p q n = p n q n Then, - 7 8 2 = - 7 2 8 2 = - 7 × 7 8 × 8 = - 49 64 Therefore, the absolute value of - 7 8 2 is - 49 64 .

Find the absolute value of - 2 3 4

We know that, In general, for any rational number p and a positive integer n , p n = p × p × p . . . . . . . × p n t i m e s and p n is called the n t h power of p . And if p q q ≠ 0 is any rational number and n is any integer, then p q n = p n q n As a negative rational number raised to an even power is positive. Then, - 2 3 4 = - 2 4 3 4 = - 2 × - 2 × - 2 × - 2 3 × 3 × 3 × 3 = 16 81 Therefore, the absolute value of - 2 3 4 is 16 81 .

Find the absolute value of - 3 2 5

We know that, In general, for any rational number p and a positive integer n , p n = p × p × p . . . . . . . × p n t i m e s and p n is called the n t h power of p . And if p q q ≠ 0 is any rational number and n is any integer, then p q n = p n q n As a negative rational number raised to an odd power is negative. Then, - 3 2 5 = - 3 5 2 5 = - 3 × - 3 × - 3 × - 3 × - 3 2 × 2 × 2 × 2 × 2 = - 243 32 Therefore, the absolute value of - 3 2 5 is - 243 32 .
