A9*8a4
Final result :
23a13
Step by step solution :
Step 1 :
Equation at the end of step 1 :
23a9 • a4
Step 2 :
Multiplying exponential expressions :
2.1 a9 multiplied by a4 = a(9 + 4) = a13
Final result :
23a13
For the secound one u multiply I belive
Its simple. You collect like terms and put them on one side of the equation
