Tolong dijawab ya 5^8 x 1/5^4 - 5^-3 =

[tex] {5}^{8} \times ({ \frac{1}{5} })^{4} - {5}^{ - 3} \\ = {5}^{8} \times ({ {5}^{ - 1} })^{4} - {5}^{ - 3} \\ = {5}^{8} \times {5}^{ - 4} - {5}^{ - 3} \\ = {5}^{8 - 4} - {5}^{ - 3} \\ = {5}^{4} - \frac{1}{ {5}^{3} } \\ = 625 - \frac{1}{125} \\ = 625( \frac{125}{125} ) - \frac{1}{125} \\ = \frac{78125}{125} - \frac{1}{125} \\ = \frac{78124}{125} [/tex]
Semoga dapat dipahami
