Answer:
x=6
Step-by-step explanation:
When we multiply exponents with the same base we add the exponents
When we divide exponents with the same base we subtract the exponents
4^3 * 4^3 ÷4^3 *4^3
We will work from left to right
Multiply means add
4^(3+3) ÷4^3 *4^3
4^6÷4^3 *4^3
Now divide means subtract
4^6÷4^3*4^3
4^(6-3)*4^3
4^3 *4^3
4^3*4^3
Multiply means add
4^(3+3)
4^6
4^6 = 4^x
The bases are the same so the exponents must be the same

Answer:
Perimeter of a rectangle = 2×(Length+Breadth)
(i) Length = 16.8 cm
Breadth = 6.2 cm
Perimeter = 2×(Length+Breadth)
= 2×(16.8+6.2) =46 cm
(ii) Length = 2 m 25 cm
=(200+25) cm (1 m = 100 cm )
= 225 cm
Breadth =1 m 50 cm
= (100+50) cm (1 m = 100 cm )
= 150 cm
Perimeter = 2×(Length+Breadth)
= 2×(225+150) =750 cm
(iii) Length = 8 m 5 dm
= (80+5) dm (1 m = 10 dm )
= 85 dm
Breadth = 6 m 8 dm
= (60+8) dm (1 m = 10 dm )
= 68 dm
Perimeter = 2×(Length+Breadth)
= 2×(85+68) =306
