Write and evaluate an exponential expression to find how much money Jacob will have in his savings in Week 5. Represent the problem with repeated multiplication and exponential expressions. Week 4 Week 5 Week 1 Week 3 Week 2 3.3.3.3.3= 35 3.3.3.3 = 34 3.3.3 = 33 3= 31 3.3 = 32 Week 5 expression: 35 Evaluate the expression: 35 = 3.3.3.3.3 = 243 Jacob will have $243 in his savings in Week 5. won't let me post the table​
