Answer 1

Answer:

3. 196 (sorry the symbols are working properly)

4. 36

Step-by-step explanation:

3. ( (2^4)^2 * 7^5 ) / ( 8^2 * 7^3 )

= ( 2^(4*2) * 7^5 ) / ( (2^3)^2 * 7^3 )

= ( 2^8 * 7^5 ) / ( 2^6 * 7^3 )

= 2^(8-6) * 7^(5-3)

= 2^2 * 7^2

= (2*7)^2

= 14^2

= 196

4. ( 2 * 3^4 * 2^5 ) / ( 9 * 4^2 )

= ( 2^(1+5) * 3^4 ) / ( 3^2 * (2^2)^2 )

= ( 2^6 * 3^4 ) / ( 3^2 * 2^4 )

= 2^(6-4) * 3^(4-2)

= 2^2 * 3^2

= 4*9

= 36

Answer 2

Answer:

(2⁴)²×7⁵/8²×7³

2⁸×7⁵/8²×7³

2×2×2×2×2×2×2×2×7×7×7×7×7/8×8×7×7×7

{2×2×7×7= 196}
