Explanation:
1)
Put the values
2^5 -7³
32-343
-311
2)
Multiply 13 and 2 and the values power will be added as it is multiplication
26 (p^1+5) (h^3+1)
26 p^6 h^4
3)
Multiply -6 and -3and the values power will be added as it is multiplication.
18 (x^1+1) (y^2+3) (z^3+4)
18 x^2 y^5 z^7
4)
Divide -40 and 2 and the values power will be subtracted as it is division
-20 ( b^7-7) (c^5-1)
-20 b^0 c^4
