Answer:
a = -9/20
Step-by-step explanation:
We can evaluate what’s on the left hand side of the equation to get what a is.
The numerator can be expressed as x^(4/5)
The denominator is x^5/4
we use the law of indices to finish this off
That would be;
x^(4/5) ÷ x^(5/4)
Using the second law of indices;
x^(4/5-5/4) = x^-9/20
Since the bases are now equal, then we equate the powers
Thus a = -9/20
The square root of 81 equals 9. This can be known through understanding the roots of perfect squares. After this, you multiply 8 x 9 to get a final answer of 72.
Add 8 to 5 and 6 on the left side of the equation. Put p on the right side. Answer is 19=p
i may not know how the triangle looks like but i assume that its a right angle triangle.
if we want to find the missing length example hypotenuese.. 3 is adjacent and 6 is opposite. Then use the formula:
c²= a²+b²
c²= 3²+6²
c²= 45
c= √45
c= 7 (nearest tenth)
hope this helps
