Please help please help.

a. 2⁴= 2×2= 16.

b. (-4)²=

since the power of two is even, the result will be positive.

4²= 2×2×2×2=16.

c. 5³*4=

d. 0.7²=0.49.

e. 5(4²+9²-121°)

5×(16×81-121°)

x°=1

121°= 1.

5×(16+81-11).

16+81-1= 96

5 ×96= 480

ANS= 480.

F. 5 5÷ 5³

5 5= 5×5×5×5×5 = 3125

5³= 5×5×5=125

3125÷125= 25.

G. 11¹0÷11–⁴ =

11¹0= 25937424601.

use negative power rule.

25937424601÷¹/11⁴

11⁴= 14641

25937424601÷ ¹/14641

use this rule a÷ b/c= a×c/b.

25937424601 ×14641/1 = 379749833583241.

H. √5²+12² - 4

√25+ 144 -4

√169-4

square root of 169=13

13-4= 9.

I. ³√-4×16

-4×16= -64.

³√64= -4

J. ⁴√50625

Rewrite 50625 as it's prime factor.

⁴√3×3×3×3×5×5×5×5.

Group the same prime factors into groups of four.

⁴√(3×3×3×3)×(5×5×5×5).

Rewrite each group if four in four exponent form.

⁴√3⁴×5⁴

Use the rule ⁴√x⁴=x.

3×5=15.
