Are you expected to use logs? If so:
+1.5%5E%283%2F2%29+=+x+
Take the log to base 10 of both sides
+log%28%28+1.5%5E%283%2F2%29+%29%29+=+log%28x%29+
+1.5%2Alog%28+1.5+%29+=+log%28x%29+
+1.5%2A.17609+=+log%28x%29+
+.26414+=+log%28x%29+
+x+=+10%5E.26414+
+x+=+1.8371+
-------------------------
+2%5E1.4+=+x+
+1.4%2Alog%28+2+%29+=+log%28x%29+
+1.4%2A.30103+=+log%28x%29+
+.42144+=+log%28x%29+
+x+=+10%5E.42144+
+x+=+2.639+
