When you have a number raised to the power of a number inside parenthesis and then it is raised to the power of another number, it can be simplified by multiplying the two exponents together.(4^4)^x = 4^32
To find x, divide the exponent on the right by the known exponent on the left:
x = 32/4
x = 8
Answer:
y = 
Step-by-step explanation:
In equations, it's important to complete an operation to both sides because if it is only completed on one then the whole equation will change and the solution will be different so it's an important rule to remember when solving equations that you have to keep the equation balanced.
→ 6 = 4x + 9y
⇒ Minus 4x from both sides to isolate 9y
→ 6 - 4x = 9y
⇒ Make 'y' the subject
→ 9y = 6 - 4x
⇒ Divide both sides by 9 to isolate 'y'
→ y = 
The unit numbers can be 2,4,6.Suppose 2 as the unit number we can form 20 numbers the same way for 4 and 6 so totally 60 numbers.
