aleksandr82 [10.1K]

Answer:

Step-by-step explanation:

21. The exponents cannot be added in the product having bases 12 and 11 because the bases are different. They can only be added if the bases are same.

22.     a)     (3¹)⁵

         b)    ⁵√(3²⁵)

          c)    (3⁵)³    ÷  (3⁵)²

23.  The distance from the Earth to moon is 22⁴ miles

The distance from the Earth to Neptune is 22⁷ miles

The distance from the Earth to Neptune  is greater by =   22⁷/22⁴ =  22⁷⁻⁴=  22³miles.

It is greater by three times

24.    8³. 8⁻⁵= 8³⁻⁵= 8⁻²= 1/8²= 1/64

1/64 ∠ 1

The student is not correct as 1/64 is less than 1.

Sin(x+24) = Cos(y-x) ; Tan(z-24) - Tan(y-z)=0<br><br> find: Cos(y-z)
Delvig [45]
<h3>Answer:</h3>

Cos(y-z) = Cos(z-24)

<h3>Step-by-step explanation:</h3>

You have two equations in three unknowns, so no solution for the unknowns is possible.

The tangent equation tells you ...

... tan(z -24) = tan(y -z)

... z -24 = y -z . . . . . . take the arctangent

... cos(y -z) = cos(z -24) . . . . take the cosine
