= 8√15
Step-by-step explanation:
Steps
2√3 x 4√5
Apply radical rule: √a√b=√ab.
√3 √5 = √3x 5
=2√3x 5 x 4
Multiply the numbers: 3 x 5= 15
=2√15 x 4
Multiply the numbers: 2 x 4 =8
= 8√15
2√3 x 4√5 = 8√15 (Decimal: 30.98386..)
So, first add 1.75 and 1.15 together. the answer? 2.9, add a zero, 2.90. then subtract 2.90 off of 5, the answer is 2.1.
