Answer:
(22•5a3b4)
Step-by-step explanation:
STEP
1
:
Equation at the end of step 1
4ab • (5a2 • b3)
STEP
2
:
Multiplying exponential expressions :
2.1 a1 multiplied by a2 = a(1 + 2) = a3
Multiplying exponential expressions :
2.2 b1 multiplied by b3 = b(1 + 3) = b4
Final result :
(22•5a3b4)
Answer:
12
Step-by-step explanation:
Because < this means less than. So therefore 5 is less than 12
The answer is 9:50. This is because 45 minus 35= 10. You subtract the leftover ten from 10:00 and get 9:50. Hope this helps!
