Answer:
(1): "x7" was replaced by "x^7". 1 more similar replacement(s).
Equation at the end of step 1
(0 - (3 • (x5))) • (2•3x7)
Equation at the end
(0 - 3x5) • (2•3x7)
Multiplying exponential expressions
3.1 x5 multiplied by x7 = x(5 + 7) = x12
Multiplying exponents:
3.2 31 multiplied by 31 = 3(1 + 1) = 32
Final result :
( -32•2x12)
