Step-by-step explanation: You are multiplying the two exponents, all you have to do is 10 × 3/5: (10×3) / (5×1) > you just make 10 a fraction by putting 10 over one. You get 6 as the new power or exponent. If (b^m)^n then it is the same as b^ (m×n)
Use formula p=m/v P is density M is mass V volume So you have the volume already now 8x5x4= 160 which is the volume P= 1800/160 after you divide you get 11.25 The density is 11.25
