Which expression is equivalent to (5x3 (4x)3?20x6320x6500x68,000x6

Answer; 320x^6We have been given the expression (5x^3 (4x)^3)first solve the whole cube power over 4x we will get 4^3=64                                                                                       (4x)^3= 64x^3The word equivalent in any expression means the simplest form of the expression form we get after simply it here simplification means multiplying the expressionNow, multiply 5x^3* 64x^3  is equal to 320x^6Therefore, given expression is equivalent to 320x^6HOPE U UNDERSTOOD PLZ MARK AS BRAINLIAST!!
