Answer:
Step-by-step explanation:
−7m+1×(−7)
7
=7
19
2 Since the power of 7 is odd, the result will be negative.
-7m+1\times -{7}^{7}={7}^{19}
−7m+1×−7
7
=7
19
3 Simplify {7}^{7}7
7
to 823543823543.
-7m+1\times -823543={7}^{19}
−7m+1×−823543=7
19
4 Simplify 1\times -8235431×−823543 to -823543−823543.
-7m-823543={7}^{19}
−7m−823543=7

5 Add 823543823543 to both sides.
-7m={7}^{19}+823543
−7m=7
19
+823543
6 Divide both sides by -7−7.
m=-\frac{{7}^{19}+823543}{7}
m=−
