Simplify Expression
Problem Statement:
There is an expression on the grid, use your knowledge about integer exponents to simplify the left side of the ' = ' and calculate the unknown exponent u of the expression to the right of ' = ' . Then answer the prompt. Reset for new problem.
```/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>
double u;
CPlot plot;

// This is a sample solution to (7^9)(7^-3)(7^-17)
plot.strokeColor("red");
plot.strokeWidth(2);
u = (9 + -3) + -17;
plot.text(u, PLOT_TEXT_LEFT, 11.5, 21);

plot.axisRange(PLOT_AXIS_XY, -12, 24);
plot.ticsRange(PLOT_AXIS_XY, 6);
plot.sizeRatio(1);
plot.plotting();```
