Answer 1

7⁰×7¹×7⁵:7⁴+2014⁰-1²⁰¹⁵

$\frac{7^0\times \:7^1\times \:7^5}{7^4}+2014^0-\left(1^{20}\right)^{15}=49$

$=\frac{7^5\times \:7^1\times \:7^0}{7^4}+2014^0-1^{15}$

$=\frac{7^5\times \:1\times \:7^1}{7^4}+1-1^{15}$

$=\frac{7^5\times \:1\times \:7}{7^4}+1-1^{15}$

$\frac{1\times \:7\times \:7^5}{7^4}$

$1\times \:7\times \:7^5=7^6$

$1\times \:7\times \:7^5$

$=7^{1+5}$

$=7^6$

$=\frac{7^6}{7^4}$

$=7^{6-4}$

$=7^2$

$1^{15} = 1$

$=7^2+1-1$

$=7^2 = 49$
