Question

Simplify and write the answer in exponenetial form [(2²)¹×3⁶]×5⁶​

Answer 1

Answer:

In right ΔABC,

tan 45° = AB/BC

1= 7/BC

BC = 7

Since BC = AD

So AD = 7

Again, from right triangle ADE,

tan 60° = DE/AD

√3 = DE/7

⇒ DE = 7√3 m

Answer 2

Answer:

1.59432300E or (30)¹³

this is your answer
